An organization can designate its own units and subunit as a guarantor, which can then fulfill the same role as a bank. This is a very important feature of setting up a unit as a guarantor, as it means that the organization does not need to have a room system with the bank.

When a organization unit is designated as the guarantor and for instance if the user wants to do a Guarantee Issuance, the following steps should be taken, for more guide follow the gif:

• Login as admin user
• Select a unit and Set Unit As Guarantor, select the products (Guarantee, Export LC, Import LC, and Standby LC) the corporate wants to work with "Unit as guarantor".
• Login as processor user
• Create a new Outgoing Guarantee deal and check the "My Bank" field
• The drop-down options should include the units which are set as guarantors under the format: "Unit name (Organization name)"
• Verify that the unit-as-guarantor is only available in the My Bank field, and not exposed in the "Advising Bank", "Local Issuing Bank" and "Additional Participants" fields.
